The imbalance between in-phase (I) and quadrature (Q) branches of down-conversion receivers creates interference between the mirror frequencies after down-conversion to the baseband. The IQ mismatch (IQMM) caused by non-ideal characteristics of I and Q paths degrades the system performance by reducing the effective signal to interference ratio. Hence, IQ mismatch compensation (IQMC) is crucial for the design of wideband systems with quadrature down-conversion architecture.
